Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1:

[0035] like Figures 1-5 As shown, a paper tube splicing device includes: a frame 1; a dual-station rotating mechanism 2, located at the bottom of the frame 1, including two paper tube fixing units 201 for fixing new and old paper tubes respectively; an old paper traction mechanism 7, located at the top of the frame 1, for traction of old paper; a new paper laying mechanism, including a lifting clamping device 3, the lifting clamping device including a pneumatic actuator and a mechanical gripper, the pneumatic actuator driving the mechanical gripper to reciprocate vertically to clamp the starting end of the new paper tube; a paper end detection sensor, located on the side of the mechanical gripper, for detecting the position of the starting end of the new paper and guiding the clamping operation; a pressing platform 4; a pressing actuator, located on one side of the pressing platform 4, for pressing the new paper and old paper onto the pressing platform 4; and a splicing mechanism, including a cutting actuator 5 and an adhesive actuator 6, connected to the pressing actuator, the cutting actuator 5 for cutting the paper of the new paper tube, and the adhesive actuator 6 for adhesively bonding the ends of the new paper and the old paper.

[0036] Specifically, the two paper tube fixing units 201 of the dual-station rotating mechanism 2 are two paper tube fixing seats, which respectively fix the new paper tube and the old paper tube. After the new paper tube is fixed on the paper tube fixing seat, the dual-station rotating mechanism 2 can rotate 180° to rotate the new paper tube to the working position for convenient subsequent work. The old paper traction mechanism 7 is located above the dual-station rotating mechanism 2. When the old paper traction mechanism 7 tractions the old paper, the old paper adheres to the surface of the pressing platform 4. The lifting clamping device 3 consists of a drive mechanism and a mechanical clamp. The mechanical clamp is driven by the drive mechanism. The paper roll moves downwards to the new paper roll. At this point, the paper roll holder, which holds the new paper roll, rotates, allowing the mechanical clamp to locate and clamp the starting end of the new paper. Driven by the drive mechanism, the mechanical clamp moves upwards, holding the starting end of the new paper. The pressing mechanism presses the new and old paper together onto the pressing platform 4, with the pressing mechanism adhering to the new paper and the pressing platform 4 adhering to the old paper. The cutting unit 5 is a cutter that cuts the new paper. The old paper traction mechanism 7 rotates continuously, causing the old paper to completely detach from the old paper roll. Finally, the bonding unit 6 bonds the ends of the new and old paper together. This dual-station design enables seamless switching between new and old paper rolls, significantly improving production continuity and reducing downtime. The traction, laying, pressing, cutting, and bonding processes are fully automated, reducing manual intervention and improving splicing accuracy and efficiency.

[0037] Example 2:

[0038] like Figures 1-5 As shown, a paper tube splicing device includes: a frame 1; a dual-station rotating mechanism 2, located at the bottom of the frame 1, including two paper tube fixing units 201 for fixing new and old paper tubes respectively; an old paper traction mechanism 7, located at the top of the frame 1 for traction of old paper; a new paper laying mechanism, including a lifting clamping device 3 for vertical movement and clamping the starting end of the new paper tube; a pressing platform 4; a pressing execution mechanism, located on one side of the pressing platform 4 for pressing the new paper and old paper onto the pressing platform 4; and a splicing mechanism, including a cutting execution unit 5 and an adhesive execution unit 6, connected to the pressing execution mechanism, wherein the cutting execution unit 5 is used to cut the paper of the new paper tube, and the adhesive execution unit 6 is used to adhesive the ends of the new paper and the old paper.

[0039] Specifically, the two paper tube fixing units 201 of the dual-station rotating mechanism 2 are two paper tube fixing seats, which respectively fix the new paper tube and the old paper tube. After the new paper tube is fixed on the paper tube fixing seat, the dual-station rotating mechanism 2 can rotate 180° to rotate the new paper tube to the working position for convenient subsequent work. The old paper traction mechanism 7 is located above the dual-station rotating mechanism 2. When the old paper traction mechanism 7 tractions the old paper, the old paper adheres to the surface of the pressing platform 4. The lifting clamping device 3 consists of a drive mechanism and a mechanical clamp. The mechanical clamp is driven by the drive mechanism. The paper roll moves downwards to the new paper roll. At this point, the paper roll holder, which holds the new paper roll, rotates, allowing the mechanical clamp to locate and clamp the starting end of the new paper. Driven by the drive mechanism, the mechanical clamp moves upwards, holding the starting end of the new paper. The pressing mechanism presses the new and old paper together onto the pressing platform 4, with the pressing mechanism adhering to the new paper and the pressing platform 4 adhering to the old paper. The cutting unit 5 is a cutter that cuts the new paper. The old paper traction mechanism 7 rotates continuously, causing the old paper to completely detach from the old paper roll. Finally, the bonding unit 6 bonds the ends of the new and old paper together. This dual-station design enables seamless switching between new and old paper rolls, significantly improving production continuity and reducing downtime. The traction, laying, pressing, cutting, and bonding processes are fully automated, reducing manual intervention and improving splicing accuracy and efficiency.

[0040] Furthermore, the waste paper traction mechanism 7 includes a rotary traction unit 701, which rotates to continuously detach the paper from the waste paper tube and maintain a taut state. Specifically, the rotary traction unit 701 is a traction roller group that uses friction or roller transmission to continuously detach the waste paper from the paper tube and maintains the waste paper in a taut state through rotational tension, preventing the paper from becoming loose or stacked.

[0041] Furthermore, the new paper laying mechanism also includes a horizontal guide plate 8, a horizontal pushing member 9, a pressing mechanism 10, a first linear drive mechanism 11, a second linear drive mechanism 12, and a first drive device 13. The horizontal pushing member 9 is fixed to the first linear drive mechanism 11, the pressing mechanism 10 is fixed to the second linear drive mechanism 12, and the horizontal guide plate 8 is connected to the first drive device 13. The first linear drive mechanism 11 drives the horizontal pushing member 9 to guide the new paper to the surface of the horizontal guide plate 8, and the second linear drive mechanism 12 drives the pressing mechanism 10 to fix the new paper to the horizontal guide plate 8. Specifically, the first linear drive mechanism 11 is a cylinder or a lead screw, which drives the horizontal pushing member 9 to push the new paper out of the paper tube and onto the surface of the horizontal guide plate 8; the second linear drive mechanism 12 drives the pressing mechanism 10 to press down, and the pressing mechanism 10 is a pressure plate to fix the new paper on the guide plate; the first drive device 13 is a motor, which drives the guide plate to rotate and is used to transport the waste paper cut by the cutting execution unit 5 to the outside of the equipment.

[0042] Furthermore, the bottom of the pressing mechanism 10 is provided with a rolling element 1001, so that the pressed paper can move along the guide surface during the movement of the horizontal guide plate 8 driven by the first driving device 13. The rolling element 1001 at the bottom of the pressing mechanism 10 is a ball or roller, which contacts the paper surface when the guide plate rotates, allowing the paper to slide along the guide surface, while keeping the paper from detaching from the guide plate through the pressing force. Low-friction movement reduces the friction between the paper and the guide plate.

[0043] Furthermore, the pressing mechanism includes a second drive device 14, a transmission assembly 15, a support frame 16, and a pressing execution unit 17. The pressing execution unit 17 is connected to the support frame 16. One end of the transmission assembly 15 is connected to the support frame 16, and the other end is connected to the second drive device 14. The second drive device 14 drives the pressing execution unit 17 to press the new paper and the old paper together via the transmission assembly 15. The second drive device 14 is a motor or a hydraulic cylinder, which drives the support frame 16 through the transmission assembly 15, causing the pressing execution unit 17 to move downward. The pressing execution unit 17 is a pressing roller or a pressure plate, which tightly presses the new and old paper together on the platform.

[0044] Furthermore, the splicing mechanism also includes a third drive device 18 and a cam mechanism 19. The cam mechanism 19 is disposed within the support frame 16, and the third drive device 18 is connected to the cam mechanism 19. The cutting execution unit 5 and the bonding execution unit 6 are linked together through the cam mechanism 19. The third drive device 18 is a motor, which synchronously drives the cutting execution unit 5 and the bonding execution unit 6 through the cam mechanism 19 to first cut off the excess part of the new paper, and then bond the new paper to the end of the old paper. The linkage control achieves the timing synchronization of cutting and bonding through a single drive source, reducing the complexity of the mechanism, improving the coordination of actions, and avoiding action delays caused by manual intervention with high-precision timing, ensuring accurate cutting and bonding positions, and improving splicing quality.

[0045] Furthermore, the paper tube splicing equipment also includes an adhesive tape supply mechanism 20, located to the side of the bonding execution unit 6. The adhesive tape supply mechanism 20 provides adhesive tape to the bonding execution unit 6 to complete the bonding of new and old paper. The adhesive tape supply mechanism 20 consists of a roller and guide rollers, continuously feeding adhesive tape to the bonding execution unit 6. The adhesive tape is either adhesive tape or hot melt adhesive strip. The bonding execution unit 6 obtains the adhesive tape by gripping or spreading it and adheres it to the bonding area between the new and old paper. Automated tape supply eliminates the need for manual replacement of adhesive materials, improving splicing efficiency and reducing labor costs. Standardized connecting adhesive tape provides stable connection strength, avoiding the randomness of traditional manual bonding and ensuring splicing reliability.

[0046] Furthermore, the bonding execution unit 6 includes a bonding actuator 601 and a linkage mechanism 602. The linkage mechanism 602 drives the bonding actuator 601 to acquire the adhesive tape at the adhesive tape supply mechanism 20 and to bond the pressed new paper with the old paper detached from the old paper tube. The linkage mechanism 602 drives the bonding actuator 601 to reciprocate: first, it grabs the adhesive tape from the adhesive tape supply mechanism 20, and then presses it onto the junction of the new and old paper, using pressure to firmly bond the adhesive tape to the paper. The linkage mechanism 602 has a precise movement trajectory, ensuring accurate positioning of the adhesive tape and avoiding deviation or skew. It completes tape picking and bonding in one action, reducing process time and adapting to high-speed production scenarios.

[0047] Furthermore, the paper tube splicing equipment also includes a paper tube conveying mechanism 21, located at the front end of the dual-station rotary mechanism 2, for conveying new paper tubes. The paper tube conveying mechanism 21 is a conveyor belt or roller conveyor, which automatically transports new paper tubes from the storage area to the front end of the dual-station rotary mechanism 2 and lifts them. Automated feeding reduces the time spent on manual handling and installation of paper tubes, improves the continuous operation capability of the equipment, and directional conveying ensures that new paper tubes arrive at the designated position in the correct posture, facilitating subsequent positioning and fixing.

[0048] Furthermore, the paper tube splicing equipment also includes a paper tube positioning mechanism 22, comprising a linear driver and a push plate. The linear driver, via the push plate, positions the new paper tube conveyed by the paper tube conveying mechanism 21 to the paper tube fixing unit 201 of the dual-station rotary mechanism 2. The linear driver is a cylinder that drives the push plate to push the new paper tube from the paper tube conveying mechanism 21 towards the fixing unit of the dual-station rotary mechanism 2. Precise positioning is achieved through a limiting device, ensuring that the paper tube axis is aligned with the fixing unit. This reduces manual adjustment time and improves material changing efficiency.

[0049] In this embodiment, the specific structure and working principle of the paper tube splicing device are as follows:

[0050] Frame 1: The main supporting structure for the entire equipment.

[0051] Dual-station rotating mechanism 2: Installed at the bottom of frame 1. Its core consists of two independently rotatable paper tube holders, used to hold old paper tubes that are about to be used up and new paper tubes ready for use, respectively. The key function of this mechanism is its ability to rotate 180°, precisely rotating the new paper tube from the preparation station to the working position, achieving seamless switching between old and new paper tubes. The paper tube holders themselves also have a self-rotating function, making it easy to find new paper rolls.

[0052] Waste paper traction mechanism 7: Installed on top of frame 1, above the dual-station rotary mechanism 2. The core is the rotary traction unit 701, which usually consists of one or more sets of traction rollers. Its function is to continuously and stably pull the waste paper from the waste paper tube through the frictional force generated by rotation, and always keep the paper in a taut state to prevent slack or accumulation. The pulled waste paper is laid flat on the pressing platform.

[0053] New paper laying organization:

[0056] Horizontal pusher 9: Fixed on the first linear drive mechanism 11, its function is to horizontally push the new paper head pulled up by the lifting clamping device 3 onto the surface of the horizontal guide plate 8.

[0057] The pressing mechanism 10 is fixed on the second linear drive mechanism 12 (such as a cylinder). Its function is to press down and fix the new paper that has been pushed onto the horizontal guide plate 8. Its bottom is equipped with a rolling element 1001 (such as a roller or ball) to allow the pressed paper to slide with low friction when the guide plate moves.

[0058] First drive unit 13: usually an electric motor, used to drive the horizontal guide plate 8 to move, the main purpose of which is to remove the new paper waste generated by subsequent cutting out of the equipment.

[0059] Pressing platform 4: A flat work surface for placing and supporting the papers to be spliced ​​(old paper is laid flat on it, and new paper is covered on top).

[0060] Pressing actuator:

[0061] Pressing execution unit 17: usually a pressure roller or pressure plate, which acts directly on the paper.

[0062] Support frame 16: Supports the pressing and pressing execution unit.

[0063] Second drive unit 14: power source, such as an electric motor or hydraulic cylinder.

[0064] Transmission component 15, such as connecting rod, gear rack, lead screw, etc., transmits the power of the second drive device 14 to the support frame 16, drives the pressing execution unit to move, and tightly presses the new paper and old paper stacked on the pressing platform together.

[0065] splicing mechanism:

[0066] Cutting execution unit 5: usually a cutter, used to cut off excess new paper on the new paper tube after pressing.

[0067] Adhesion execution unit 6: The core includes adhesive execution components (such as glue applicator) and linkage mechanism, which are responsible for obtaining adhesive tape and pressing / applying it to the joint between the old and new paper for bonding.

[0068] Third drive unit 18: power source, usually an electric motor.

[0069] Cam mechanism 19: Installed inside the support frame 16, the third drive device drives the cam mechanism to operate, precisely coordinating the actions of the cutting execution unit and the bonding execution unit. First, the new paper is cut, and then bonding is performed. This linkage ensures that the action sequence is accurate.

[0070] Adhesive tape supply mechanism 20: Located on the side of the bonding execution unit, typically an adhesive tape reel and guide roller system, used to continuously and automatically supply adhesive tape (tape or hot melt adhesive strip) to the bonding execution unit.

[0071] Paper tube conveying mechanism 21: Installed at the front end of the dual-station rotary mechanism 2, usually a conveyor belt or roller conveyor, responsible for automatically conveying new paper tubes from the storage area to the designated position of the equipment (near the dual-station rotary mechanism).

[0072] Paper tube positioning mechanism 22: includes a linear drive (such as a cylinder) and a push plate. Its function is to accurately push the new paper tube from the paper tube conveying mechanism onto the idle paper tube fixing seat of the dual-station rotary mechanism and ensure that its position is correct (usually by using a limit device to ensure axis alignment).
